In the heartfelt episode, Archie gets a call that changes his entire world — his father died after saving a woman on the side of the road. In classic Fred Andrews, Perry’s character, fashion, he took the hit from a speeding truck, saving the woman in the process.

That woman was none other than Shannen Doherty, Perry’s “90210” co-star and dear friend.

In the episode, Archie picks up his father from a town nearby and July 4 festivities turned into a parade for Fred and Luke, to honor the actor and character.

Showrunner Roberto Aguirre-Sacasa took to Twitter to add details of the special episode.

“With an episode that honors our friend Luke. It’s an episode that’s bursting with sadness, but even more so with love,” he wrote. “I’m humbled by the outstanding work everyone did on it. I hope you like it, Luke. We miss you every day.”
